IMPROVEMENT IN SCHOOL-DESKS.

Specification forming part of Letters Patent No. 158,271, dated December29, 1874; application led' July 7, 1874. i

- which will enable others skilled in the art to which it pertains tomake and use the same, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specification.

The nature of my invention consists more particularly in theconstruction and arrangement of the devices for supporting a schooldesk,as will be herein after more full y' set forth.

In the accompanying drawing, Figure l is a rear elevation ot' aschool-desk embodying my invention; and Fig. 2 is a cross-section of thesame through the line fr, Fig. l.

D represents the book-case of a school-desk, the front C of which formsthe back for the seat. The front part of the book-case D is supported bymeans of two crossed legs or supports, A A, which stand lengthwise withthe desk, and extend from the licor to the corners of the book-case.These supports are fitted closely to the ends of the book-case and thetop of the desk, thus both irmly supporting and bracing the desk,whether fastened to the oor or not, and yet without any straincalculated to draw out the screws with which the desk is put together.The legs or supports A are let into each other where they cross,

and in the cross of the supports is placed and notched down a horizontalbar, B, which connects and braces two or more desks, thus making themseltsupporting. This bar by this mode or" attachment becomes low enoughto receive the seat on top, and when the seat is turned up the bar canreadily be stepped over, thus obviating the only objection to this kindof desks. The back part E of the seat is made fast to the bar B and thecrossed supports A A, while the front and main part G of the seat ishinged to the back part, so as to be turned up and down, as may berequired. The rear part of the book-case is supported and braced fromthe horizontal bar B by means of a double metallic brace, H.

A school-desk of this construction is equally as strong and durable, andfar more economical, than those nowr generally used, which have ironside frames.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

'lhe combination of the book-case D, back C, seat E G, crossed supportsA A, horizontal bar B, and double brace H, all constructed substantiallyas and for the purposes herein set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses. Y

FRANCIS M. GILCHEIST.
